I have seldom come across unix multiuser environments getting used anymore for servers. Its generally just one user on one physical machine now a days. I understand run0's promise is still useful but i would really like to see the whole unix permission system simplified for just one user who has sudo access.
Yeah but elevated permissions may be needed from time to time anyway. Either on the client, the baremetal server or the container. Running everything as root is even for containers not recommended. Considering how popular these have become, it's a bit of an irony that systemd isn't available on the container without considerable detours.
